No, Slurm has to launch the batch script on compute node cores and it
then has the job of launching the users application that will run
something on the node that will access the GPU(s).

Even with srun directly from a login node there's still processes that
have to run on the compute node and those need at least a core (and some
may need more, depending on the application).
